Nanoimprinting of Biomimetic Nanostructures

Biomimetic gyroid nanostructures exceeding their natural origins

Using optical two-beam lithography with improved resolution and enhanced mechanical strength, we demonstrate the replication of gyroid photonic nanostructures found in the butterfly Callophrys rubi. These artificial structures are shown to have size, controllability, and uniformity that are superior to those of their biological counterparts. In particular, the elastic Young's modulus of fabrica...

Biomimetic isotropic nanostructures for structural coloration.

Many species of birds have feathers that are brilliantly colored without the use of pigments. In these cases, light of specifi c wavelengths is selectively scattered from nanostructures with variations in index of refraction on length-scales of the order of visible light. [ 1 ] This phenomenon is called structural color. The most striking examples of structural color in nature are iridescent co...

Biomimetic, synthetic HDL nanostructures for lymphoma.

New therapies that challenge existing paradigms are needed for the treatment of cancer. We report a nanoparticle-enabled therapeutic approach to B-cell lymphoma using synthetic high density lipoprotein nanoparticles (HDL-NPs). HDL-NPs are synthesized using a gold nanoparticle template to control conjugate size and ensure a spherical shape. Like natural HDLs, biomimetic HDL-NPs target scavenger ...

Ubiocompatible and Biomimetic Self-assembly of Functional Nanostructures

Bottom-Up Synthesis and Sensor Applications of Biomimetic Nanostructures

The combination of nanotechnology, biology, and bioengineering greatly improved the developments of nanomaterials with unique functions and properties. Biomolecules as the nanoscale building blocks play very important roles for the final formation of functional nanostructures. Many kinds of novel nanostructures have been created by using the bioinspired self-assembly and subsequent binding with...
